LAWN-SPRINKLER.

SPECIFICATION forming part of Letters Patent No. 581,785, dated May 4,1897. Application filed June 12, 1896. Serial No. 595,322- (No model.)

To aZZ whom it may concern.-

Be it known that I, JOSEPH H. SMITH, of Vashingtomin the District ofColumbia, have invented certain new and useful Improvements inLawn-Sprinklers; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention contemplates certain new and useful improvements inlawn-sprinklers.

The object of the invention is to provide a device of this characterwhich will comprise advantages in point of simplicity, inexpensiveness,and durability.

The invention will be hereinafter fully set forth, and particularlypointed out in the claims.

In the accompanying drawings, Figure l is a view in side elevation,illustrating my improved sprinkler. Fig. 2 is a plan view thereof withthe cover removed. Fig. 3 is a vertical sectional view on the line as,Fig. 2. Fig. 4 is a detail. Fig. 5 is a bottom plan view of the coverand its adjuncts. Fig. (3 is a detached view of the stationary head.

Referring to the drawings, A designates the sprinkler as an entirety; a,a pipe-section having a Tjoint, into which opens a hose, as a, forsupplying water, while in the lower portion of this coupling is secureda supportingrod a by which the sprinkler can be positioned at anydesirable point, the lower end of said rod being reduced, so that it canbe readily stuck into the soil or ground.

B is the stationary head, mounted 011 the upper end of pipe a. This headis in the form of a disk having an upper circumferential flange b,forming a surrounding passageway b. At one side this flange is cut awayto form an outlet b flange and the lower opening h in which the pipe ais screwed, is an inner flange 12 in which is formed an opening Z1 toallow water from the pipe to enter the passage-way b.

C is a disk designed to fit snug down on the flange 11 against which itis firmly held by screws cl, screwing down into threaded holes in thebottom of head B, said holes not passing entirely through the latter.This disk for about one-third of its circumference is widened, as at d,the widened portion extend- Ooncentric with this ing over thepassage-way Z) and fitting snug against the flange b for one-half thecircumference of the latter. One end of this widened portion has adepending flange diwhich closes the passageway at that point, the otherend being open to allow of the free outflow of water.

D is a rotary head inclosing the stationary head and loose to revolvearound the latter under the action of the water discharged therefrom.This rotary head embodies a cylindrical box a and a cover a, the latterbeing held to the former by nutted bolts 6 In the bottom of box 6 is ahole 6 to accommodate a boss or enlargement on pipe a, permitting thebox to freely rotate, said box being pivoted by a short stud 6,extending from the top of disk 0 and fitting in a circular recess in thebottom of cover 6. In an opening in the cylindrical flange of this headis fitted a plate 9, having numerous holes 6' to allow of the dischargeof water as the head is rotated, or said holes may be formed direct insaid flange.

E E are two blades or wings mounted at right angles to one another onthe ends of a shaft f, loosely mounted in the cover 6, pockets orrecesses f being formed in the latter to accommodate said wings orblades. As one of the latter is closed into its pocket the other islowered into the passageway b by the rocking of shaft f. This shaft isthus caused to partially rotate when either of the blades or wingsengages a curved in g f projectin g upwardly from the bottom ofpassageway Z), said lug being adjacent to the closed end of the widenedportion (Z.

The shaft f is so mounted on the cover that as one blade is closed intoits pocket upon engagement with the lug f the other blade, as it clearsthe open end of said widened portion d, is lowered into the passage-Wayb, so as to receive the force of the water discharged by the stationaryhead. In this way the rotary head is constantly rotated, and the wateris discharged therefrom through the series of holes in the cylindricflange.

From what has been said the advantages of my invention will be readilyunderstood. Itwill be noted that as the Water is discharged from thestationary head into the circular passage-way thereof it will intraveling to its outlet engage one of the blades depending in saidpassage-way and cause the rotation of the rotary head, the water leavingthe latter through its outlet-holes. A sprinkler thus constructed isextremely simple and inexpensive and not liable to get out of order.Another advantage is that there is no waste of water, and the sprinklercan operate under a small force or supply.

I claim as my invention 1. Asprinklercomprisingastationaryhead intowhich the Water-pipe opens, said head having inlet and outlet openings,and a rotary head inclosing said form er head and carryingpivotally-mounted blades or win gs designed to be alternately loweredinto the line of passage of the water to said outlet, as set forth.

2. A sprinkler comprising a stationary head into which the water-pipeopens, said head having a circular passage-Way, a bridge over a portionof said passage-way, and a water inlet and outlet, and a rotary headinclosing said former head and pivoted blades carried by said rotaryhead and designed to be alter-, nately lowered into said passage-way,substantially as set forth.

3. A sprinkler comprising a stationary head into which the water-pipeopens, said head having inlet and outlet openings, a rotary headinclosing said stationary head, a shaft carried by said rotary head, andblades or wings on the ends of said shaft at right angles to each other,as and for the purpose stated.

4. A sprinkler comprising a stationary head into which the water-pipeopens, said head having a circular passage-Way and an inlet and outletfor the water, a flange over a por tion of said passage-way, a rotaryhead inclosing said stationary head having pockets orrecesses, and arock-shaft mounted in said cover and having wings or blades on its endsarranged at right angles to each other, substantially as set forth.

5. A sprinkler comprising a stationary head into which the water-pipeopens, said head having inner and outer concentric flanges withcut-aways forming inlet and outlet openings for the water, and acircular passageway, a disk secured to said inner flange having a flangeextended over a portion of said passage-way, a stud or post extendingfrom said disk, a rotary head comprising a cylindric box havingoutlet-holes, a cover, a rockshaft mounted on said cover, blades orwings on the ends of said shaft at right angles to one another, saidcover having a hole to accommodate said stud or post, and a lug in saidpassage-way designed to effect the turning of said shaft, substantiallyas set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
